JE Pistons 07-13 BMW N54B30 Bore 85 / Oversize 1.00 / Dome Volume -22.7 / Set of 6

If you're rebuilding the engine in your 2007-2013 BMW with the N54B30 engine, especially for performance applications, a strong set of pistons is crucial. JE Pistons has been making forged pistons for decades, and this set is built specifically for your engine. They are designed to handle the demands of high-performance builds, offering a solid foundation for increased power and durability.

These pistons are forged in the USA from 2618 aluminum, a material known for its high tensile strength, which is exactly what you need when pushing an engine beyond its stock limits. JE's proprietary Forged Side Relief (FSR) design helps reduce friction and weight by using a narrower skirt and a shorter wrist pin. Some applications also include an accumulator groove to help manage combustion pressure, improving ring seal and keeping power consistent. A skirt coating, if included for your specific application, further reduces friction and wear, contributing to quieter operation and longer life for both the piston and cylinder walls.

This set includes everything you need to get your engine rebuilt: the pistons themselves, high-quality wrist pins, locks, and JE's Pro Seal premium piston rings. Remember, these pistons are 1.00 inch oversize, meaning they are 0.040 inches larger in diameter than the standard bore size. This is important to consider when machining your cylinders. Please note that this part is not CARB approved and cannot be shipped to California.
